The Sky Blues got back to winning ways in League Two action, as they left it late to leave Adams Park with all three points on a freezing night.
Tom Bayliss was brought down in the area on 81 minutes and Marc McNulty stepped up to score his 17th goal of the season and lift City within three points of the play-offs.
It was a quiet opening to the game, with the first shot of the game not coming until the 15th minute, when Wycombe midfielder Luke O’Nien tried his luck from range, but it was comfortable for Lee Burge who got down well.
Just a minute late and the Sky Blues had their first effort on goal as Tom Bayliss picked the ball up and shifted it onto his right to create some space and he managed to get a shot away, but only as far as the side netting.
The Sky Blues looked the better side in the first half and just before the half hour mark, great play from Jonson Clarke-Harris created an opportunity for Marc McNulty when JCH cut the ball back to his strike partner, but his effort was blocked.
Clarke-Harris was involved again moments later, when he stood over a free-kick from around 25 yards, but his shot was deflected behind for a corner, which fell to captain Michael Doyle, but he fired over.
The hosts were finding it difficult to get a hold of the game and their next shot was from Marcus Bean from range, but it went well over the bar.
Wycombe’s next effort at goal came from Adebayo Akinfenwa, as he was on the end of a header, which was comfortably caught by Burge, in what would prove to be the last chance of the first 45 minutes.
After the break it was the Chairboys who had the first chance as a flick on from Akinfenwa was deflected to Nathan Tyson and he made Burge produce a great stop to deny the forward.
Kyel Reid was brought on for Jordan Shipley after 54 minutes and he was involved in a good opportunity for the Sky Blues as he did well down the left and picked out McNulty in the area, but his effort was deflected behind for a corner, which was later cleared.
City began to grow into the second half and continued to hunt for a breakthrough, this time it was a Jack Grimmer ball into the box was met by the on running Tom Bayliss who couldn’t get his volley on target.
Wycombe were awarded a free-kick on 77 minutes and the ball landed at the feet of Dan Scarr on the half-volley, but he couldn’t direct it goalwards.
With 80 minutes on the clock, Tom Bayliss won the ball inside the Wycombe area and ran towards goal, cut inside in the box and was brought down which saw the referee point to the spot.
Who else but Marc McNulty stepped up to take the penalty and he made no mistake in placing it into the bottom corner to give City the lead.
